The embodiment of the invention provides an unmanned aerial vehicle monitoring air pollution data and three-dimensional GIS fusion display method. The method comprises the following steps that the flight path and monitoring data of an unmanned aerial vehicle are obtained in real time; drawing an uninterrupted grid in real time based on a Cesium three-dimensional GIS platform according to the acquired flight path and monitoring data; and generating a three-dimensional thermodynamic diagram and volume rendering visualization representation of vertical distribution of pollutant concentration according to the staged accumulated atmospheric pollutant concentration value in the monitoring data. According to the embodiment of the invention, the characteristics that the three-dimensional map is visual and stereoscopic and is close to the real world are combined with the atmospheric monitoring advantage of the unmanned aerial vehicle, and the flight path and flight height of the unmanned aerial vehicle are comprehensively displayed based on the three-dimensional geographic information system technology. The surrounding terrains and live-action buildings are fused with diversified three-dimensional visual expression simulation of unmanned aerial vehicle detection values, a digital twin base is constructed, and the diffusion and evolution process of atmospheric pollution in the real world is better simulated.
Description
technical field [0001] The embodiments of the present application belong to the technical field of big data, and in particular, relate to a method for integrating and displaying air pollution data monitored by a drone and a three-dimensional GIS. Background technique [0002] In recent years, how to obtain accurate, reliable and timely basic environmental data conveniently, quickly and at low cost has become the focus and difficulty of technical research. The traditional methods of measuring the vertical distribution of atmospheric pollutant concentrations have their own limitations. For example, the measurement height of aircraft aerial surveys and lidars is generally above 1km, and the monitoring of the vertical distribution of pollutants below 500m is limited, and the procedures are complicated, and the airport and weather conditions are complicated. The problems of high condition dependence and high cost; the moored boat is limited by meteorological conditions, and has p...
